Can I view the image on my laptop simultaneously with the projector?
Your laptop may support this feature. Try the following.
If you're using a PC notebook:
Press the function key that lets you display on an external monitor. It's often labeled with an icon such as , but it may also be labeled CRT/LCD. You may have to hold down the Fn key while pressing it. Allow a few seconds for the projector to sync up after pressing it. Check your laptop's manual or online help.
On most systems, the key lets you toggle between the LCD screen and the projector, or display on both at the same time. Allow a few seconds for the projector to sync up after pressing it.
Depending on your computer's video card, you might need to use the Display utility in the Control Panel to make sure that both the LCD screen and external monitor port are enabled. See your computer's documentation or online help for details.
If you're using Macintosh OS X:
Select System Preferences from the Apple menu and click Display or Displays.
Click Detect Displays.
Do one of the following:
Mac OS X 10.6.x users: Click Show displays in menu bar.
Other Mac OS X users: Make sure the VGA Display or Color LCD dialog box is selected, click the Arrangement or Arrange tab, then make sure the Mirror Displays checkbox is selected.
